A power operated knife comprises a blade supporting structure supporting an annular blade for rotation about a central axis. The blade and blade supporting structure are engagable along bearing contact locations that are spaced apart in a direction parallel to the axis so that the blade is stabilized both radially and axially as the knife operates. The blade supporting structure comprises a split blade housing member that is radially expandible and contractible to receive the blade. The split blade housing member and blade engage along relatively short lines of bearing contact that serve to minimize friction and blade heating when the knife operates. The bearing locations are spaced apart both circumferentially around the blade perimeter and in the direction of the axis so that the blade position is stabilized during operation of the knife.

Apparatus and method for cutting meat that enables a worker to repeatedly and consistently guide a securely clamped carcass through the cutting area of a saw without exposing his or her hands to the saw's cutting implement. The operator sets a carcass in a set of clamps. Tightening of the clamps, alignment of the carcass with respect to the saw blade, and movement of the clamps and carcass through the cutting area is done with controls located on the apparatus at locations safely remote from the cutting area. Alignment, done with a laser beam, is precise and repeatable. Conveyors built into the apparatus carry the useful and scrap parts of the carcass away for convenient and safe disposal. The hands-free cutting operation minimizes human contact with the meat being cut, thereby enhancing hygiene.
